You can put this solution on YOUR website! 1.Edna is 31 years younger than her father. The sum of their ages is 47.. Find the ages.
---
Let her father's age be "x".
Then Edna is "x-31" years old.
-------------------
Equation:
x + x-31 = 47
2x = 78
x = 39 yrs (father's age)
x-31 = 8 yrs (Edna's age)
